Robin, I apologize for getting your hopes up and now suddenly doing a 180. But after going back and comparing yours side-by-side to some authentic JFK examples that I thought yours resembled, I do now see too many differences to say that this is authentic. I now think that this may have simply been the work of a forger. Since I do see that the seller is accepting of returns, I would do that. If he/she hasn't shipped yet, I would just get the sale cancelled. If they have shipped, I would just send it right back. It's just too much money to risk. Again, sorry for the confusion.
